Fuck

"Fuck" is a potent work, although it's force has been diminished of late by its excessive use.  It's now in the spoken vocabulary of both men and women, young and old, rich and poor. And for adolescents it still has the power of jolt parents, even if they themselves are ardent fucksters.

Movies use the work a lot, with the tacit assumption that everyone talks that way. TV lags behind with bleeped out fucks that make us co-conspiritors when we mouth the word ourselves. Sometimes "fuck" becomes a bit impotent when it's used in a lazy and predictable way.

For those who choose to maintain a vocabulary of only  10-15 words, "fuck" is useful because it can be used as a noun, a verb, an adjective, an adverb, an exclamation and an ejaculation. For those with larger vocabularies, it might be helpful to learn how to say "fuck" in two or three foreign languages. This adds a little class and impresses friends and associates.

It can be fun (say at a party) to have someone follow you around and make a beeping sound each time you would likely say "fuck." Also to throw off your friends, you might start saying "kcuf" in  a forceful voice.
